<p>By default, the ILM service is in the <code class="literal">RUNNING</code> state and manages
all indices that have lifecycle policies.</p>
<p>You can stop index lifecycle management to suspend management operations for all indices.
For example, you might stop index lifecycle management when performing scheduled maintenance or making
changes to the cluster that could impact the execution of ILM actions.</p>

<div class="admon_content">
<p>When you stop ILM, <a class="xref" href="snapshot-lifecycle-management.html" title="SLM: Manage the snapshot lifecycle">SLM</a>
operations are also suspended.
No snapshots will be taken as scheduled until you restart ILM.
In-progress snapshots are not affected.</p>

<div class="pre_wrapper lang-console">
<pre class="programlisting prettyprint lang-console">GET _ilm/status</pre>
</div>
<div class="console_widget" data-snippet="snippets/1132.console"></div>
<p>Under normal operation, the response shows ILM is <code class="literal">RUNNING</code>:</p>

</h3>
<p>To stop the ILM service and pause execution of all lifecycle policies,
use the <a class="xref" href="ilm-stop.html" title="Stop index lifecycle management API">Stop API</a>:</p>
<div class="pre_wrapper lang-console">
<pre class="programlisting prettyprint lang-console">POST _ilm/stop</pre>

<div class="console_widget" data-snippet="snippets/1133.console"></div>
<p>ILM service runs all policies to a point where it is safe to stop.
While the ILM service is shutting down,
the status API shows ILM is in the <code class="literal">STOPPING</code> mode:</p>
<div class="pre_wrapper lang-console-result">
<pre class="programlisting prettyprint lang-console-result">{
  "operation_mode": "STOPPING"
}</pre>
</div>
<p>Once all policies are at a safe stopping point, ILM moves into the <code class="literal">STOPPED</code> mode:</p>
<div class="pre_wrapper lang-console-result">
<pre class="programlisting prettyprint lang-console-result">{
  "operation_mode": "STOPPED"

</h3>
<p>To restart ILM and resume executing policies, use the <a class="xref" href="ilm-start.html" title="Start index lifecycle management API">Start API</a>.
This puts the  ILM service in the <code class="literal">RUNNING</code> state and
ILM begins executing policies from where it left off.</p>
